IMPROVEMENT lN-SWIVELS FOR WATCHES AND LOCKETS.

Specification forming part of Letters Patent No. 201,357, dated March19, 1878; application filed February 2, 1877 To all whom it may concern:

Be it known that I, BEVERLY '1. PAGE, of Salem,in the county ofWashington and State of Indiana, have invented a new and usefulImprovement in Swivels for Watches and Lockets, which improvement isfully set forth in the following specification and accompanyingdrawings, in which- Figure 1 is a vertical longitudinal section of myimproved swivel for watches and lockets. Fig. 2 is a like view with theswivel thrown open. Fig. 3 is a cross-section in the line as w ofFig. 1. Fig. 4. is a view of my improved watch and locket swivel,similar to. Fig. 1, with its interior packing (shown in Fig. 5) removed.

The object of my invention is to furnish a device known as a swivel bywhich to connect a watch or a locket to a safety guard or chain, and bywhich the watch-ring or locketring to which the swivel is applied shallbe protected from undue wear by reason of the articulation of the swivelupon the watch or locket ring. Heretofore this class of swivels havebeen so constructed as to permit a metal frictional bearing upon thering, the ring be- 7 ing loosely applied to the swivel, in such manneras to allow an automatic articulation of the swivel thereon during theordinary manipulations of the watch or locket, and thus have aninjurious wearing contact constantly occurring between the metal of thering and the swivel, by which both the ring and swivel becomeprematurely worn, and which, if made of gold, are expensive to replace.

Figs. 1 and 2 of the drawings show my improved swivel complete in itsseveral parts, with its main halves or portions A and A hinged together,as at b-the screw-stem c, screw-cap c, and stem-ring 0 above the line 00as, all being of the ordinary construction. Below the line 00 a," theparts A and A, instead of being made solid, are of box form, asindicated in Fig. 3, the parts i d and "L in said figure constitutingthe three walls of the box, thus leaving an interior recess, 0 in eachof the parts A A, as represented in Figs. 3 and 4. Fig. 5 representspacking-pieces d (1 made in form as shown, adapted to be fitted orseated into the chambers or recesses c of Fig. 4, the packing d beingadapted to be seated in the main portion A, and the packing d in themain portion A of said figure.

It will be seen by reference to Figs. 1, 2, and 4. that the lowerextremity of the main half A of my. swivel is made in the form of a cam,through which the hinge-pin at 1) passes, in order to connect the twomain portions A A together. In rear of the working-face of this cam thecam is cut away, as at m in Figs. 2 and 4, so as to form a depression,in rear of which the packing d can seat itself when placed in the recess0 of the main portion A. It will also be seen that the working-face c ofthe cam, when thrown into position, as shown in Fig. 1, affords such abearing against the lower extremity of the packing d as will force andretain it into its seat, while the upper extremity s of the packings d dare prevented from endwise displacement by projecting portions 8 on eachof the halves A A of the swivel, the walls 1' 13 at the same timepreventing lateral displacement. The packing d d should be made of somenon-metallic, soft, elastic substance; and, preferably, for such -packing I use cork.

By reference to Fig. 4 it will be seen that a large central opening, P,exists in the swivel before the packing-pieces d d areinserted therein,as shown in Figs. 1, 2, and 3, and

that when the packing-pieces are inserted in the recesses c all thatportion of the packing included within the circle of dotted lines, as at01 Fig. 1, projects beyond contact with any part of the swivel, and isintended to close in upon the ring of the watch or locket placed in thesmall opening 19. This opening 19, in practice, is made of considerablyless diameter than the ordinary diameter of a watch or locket ring, sothat when the ring of a watch or locket is applied therein, and theswivel closed, as represented in Fig. 1, the ring will be firmly claspedby the packing d d with a soft yielding pressure, and thus prevent anunnecessary articulation of the swivel upon the'ring, while at the sametime, if the swivel is made to move upon the ring from any causeincident to its use, there will practically be no injurious or prematurewearing away either of the metal of the ring or the packing of theswivel.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is- I 1. A chambered portion, A, formed on asWive1-stem,c, in combination with a chambered portion, A, formed on asection of the swivel-stem, substantially as and for the purposedescribed.

2. In combination with the chambered portions A A of the swivel, theyielding packingpieces d al substantially as and for the purposedescribed.

3. The combination of the cam-face formed on the portion A of theswivel, the projections 8 s, and side walls 2 6 formed on the portions AA of the same, and the packingpieces d al substantially as and for thepurpose described.

4. A Watch or locket swivel provided with a yielding or expansible eye,19, substantially as and for the purpose described.

Witness my hand in the matter of my application for a patent forimprovement in swivels for Watches and lockets this 29th day of January,1878.
